In their response, UNM is trying to debunk Leo's claim that he met with "Booster #14" in his car 2 miles from Leo's high school, by challenging the timeline, including in their response that the booster had to do all of that and respond to an email about a "pathology report" by 2:52 PM.
They are going to extreme lengths, as well, claiming it takes 10 minutes to get to his sister's car, then another 10 minutes to drive 2 miles. They want to make it seem impossible, but here's the reality:
Leo got out of class at 1:30. He could have got to his car and on his 2-mile trip by 1:31 (walk out of class, get in his sister's car parked out front and take off), meeting the booster by 1:34. Leo claimed the meeting took approximately 10-15 minutes, but that was clearly just an estimate for the NCAA investigator. I doubt he tracked the time with his watch. Very well could have been done by 1:40. And for all anyone knows, Leo may have meant to include the drive over in his estimate.
That would have given the booster 1 hour and 12 minutes to drive the 60+ miles back to his office in Ridgeland and answer the email he claims he answered from his office at 2:52. Google maps tells us the drive from Brookhaven to Ridgeland departing around that time would take about an hour (assuming he wasn't driving over the speed limit), giving the booster and Leo a good 12 minute cushion in the timeline.
Now consider the above is one of the big things the UNM legal team is counting on to discredit Leo's account, and you get another idea how desperately they are grasping at straws.
